Error while trying to connect to RM/CLM with OSLC4J
![]() I am working on Jazz CLM deployment. We are using Jazz CLM 6.0.3 with enterprise type topology and Jazz Authorization Server to manage Authentication, Authorization and SSO. I should also precise that while all the CLM component (RM, JTS, DM) are behind an reverse-proxy to unify the URL, this is not the case of the JAS server.
I would like to be able to connect to this platform (RM module for example) with some java client build on top of OSLC4J but I am facing a connection issue. The error is not present with a CLM 6.0.2 platform and without usage of Jazz authorization Server. As example, I am able to reproduce it from a simple connection class below:
import org.apache.http.HttpStatus; import org.eclipse.lyo.client.oslc.OSLCConstants; import org.eclipse.lyo.client.oslc.jazz.JazzFormAuthClient; import org.eclipse.lyo.client.oslc.jazz.JazzRootServicesHelper;
import java.util.logging.Logger;
public class Connexion {
private static final Logger logger = Logger.getLogger(Connexion.class.getName());
public void connect() {
String webContextUrl = "https://clm.server.org/rm"; String authUrl = "https://clm.server.org/jts"; String user = "userid"; String passwd = "passwd"; String projectArea = "RM PROJ";
try {
JazzRootServicesHelper helper = new JazzRootServicesHelper(webContextUrl, OSLCConstants.OSLC_RM_V2); JazzFormAuthClient client = helper.initFormClient(user, passwd, authUrl);
if (client.formLogin() == HttpStatus.SC_OK) { String catalogUrl = helper.getCatalogUrl(); } } catch (Exception e) { e.printStackTrace(); } } }
The exception trace that I get when I try to connect is the following:
java.lang.IllegalStateException: Target host must not be null, or set in parameters. at org.apache.http.impl.client.DefaultRequestDirector.determineRoute(DefaultRequestDirector.java:706) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:356) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:820) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:754) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:732) at org.eclipse.lyo.client.oslc.jazz.JazzFormAuthClient.followRedirects(JazzFormAuthClient.java:204) at org.eclipse.lyo.client.oslc.jazz.JazzFormAuthClient.formLogin(JazzFormAuthClient.java:149) at com.mathworks.toolbox.oslc_dng.OslcConnection.login(OslcConnection.java:80)
